Abstract (en)
[origin: US2014000560A1] There is provided a gas engine fuel gas supply device in which a fuel gas flows along the axial direction on the outer circumferential side of an inlet valve rod, and is supplied into the inlet path in a cylinder head. In the device, in the inner circumferential surface of a sleeve slidably fitted with a projection, the projection being a portion of the inlet valve rod, there is provided a suction hole situated within the region of movement of the projection, and to be opened and closed in response to the movement of the inlet valve rod, and a fuel gas injection hole is formed in the bottom end face of the sleeve communicating with the suction hole. The device is characterized in that the sleeve is disposed so as not to protrude into the inlet path.
